If i bought tires from 4tire.ca i could retail them at the same price as you have listed.
Do you know where my profit would be. $0.42 a tire. Plus the applicable taxes right?.

But, do ALL taxes received from sales go to the gov.
Nope. Only a percentage if your sales are low.

And if you can prove that your profit is $0.42 a tire they dont ask for much as the product has taxes already paid.
$50.56 a set for doing nothing. You could sell 700 sets like that before having to remit.

Thats neat
